Toth isotherm

WebOf the two-parameter isotherms, Temkin isotherm was the best to describe the experimental data. Three-parameter isotherms have higher regression coefficients (>0.99) and lower relative errors (5%) than two-parameter isotherms. The best fitting isotherm was the Sips followed by Toth and Redlich-Peterson isotherm equations. WebToth isotherm . Unlike Sips model that does not satisfy the low pressure limit, the Toth isotherm is capable of satisfying both high and low pressure limits as well as the Henry’s law. 1,39 This equation describes well many systems with sub-monolayer coverage. The Toth isotherm is described by the following equation:
